[Scons-users] Is it possible to use Copy Action Functions outside of SConscript?

It is screwy I agree with you :)
We have two different version of open splice, one on windows and one on
linux.
When scons invoke
'idlpp -S -l cpp -d ' + variantDirOutput + ' $SOURCE'
on windows, there is no problem, it works
When scons invoke the same command on linux, I get the following error :
idlpp -S -l cpp -d build/debug/fwk/dds_model fwk/dds_model/MaxSim.idl
"build/debug/fwk/dds_model/MaxSimDcps.idl", line 7: can't find include file
MaxSim.idl
As you can see the opensplice version of linux doesn't like the variantdir,
he is not aware of MaxSim.idl, located in src dir. This is the reason why
I am trying to copy the source MaxSim.idl to the variant dir.
Now, this bring back the question of duplicate=0. Yes, when I am calling
my SConscript, I am giving duplicate=0. In this unique case, duplicate=1
should work I guess, but it is unfortunately not a solution in our current
architecture. We have a top down approach where all SConscript are blindly
called from the SConstruct with duplicate=0 . SConstruct has no clues which
env is needed, he gives a class containing multiple env and SConscript
takes the decision which env to take. All decisional stuff are inside
SConscript
This serve us well so far. We just migrated a project containing almost
600 make files. That is the only case were duplicate=1 would be needed.
So, you have the full context of my screwy fix =)
